NOW, THEREFORE, for and in consideration of the premises and in order to induce Purchasers to make the Loans, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, each Guarantor hereby jointly and severally agrees as follows:

1. Definitions: Capitalized terms used herein without definition and defined in the Purchase Agreement are used herein as defined therein. In addition, as used herein:

“Bankruptcy Code” shall mean the Federal Bankruptcy Reform Act of 1978 (11 U.S.C. §101, et seq.), as amended and in effect from time to time thereunder.

“Obligations” shall mean (i) all obligations, liabilities and indebtedness of every nature of each Company from time to time owed or owing to the Purchasers and Agent arising under, out of or in connection with the Purchase Agreement, the Notes, the Loans and the other Transaction Documents, including, without limitation, the principal amount of all debts, claims and indebtedness, accrued and unpaid interest and all fees, taxes, indemnities, costs and expenses, whether primary, secondary, direct, contingent, fixed or otherwise, heretofore, now and/or from time to time hereafter owing, due or payable, whether before or after the filing of a bankruptcy, insolvency or similar proceeding under applicable federal, state, foreign or other law and whether or not an allowed claim in any such proceeding, and (ii) all obligations, liabilities and indebtedness of every nature of any subsequent Guarantor from time to time owed or owing to the Purchasers and/or Agent, under or in respect of this Guaranty, the Pledge Agreement, the Security Agreement, the Purchase Agreement, the Notes, the Loans and the other Transaction Documents, as the case may be, including, without limitation, the principal amount of all debts, claims and indebtedness, accrued and unpaid interest and all fees, taxes, indemnities, costs and expenses, whether primary, secondary, direct, contingent, fixed or otherwise, heretofore, now and/or from time to time hereafter owing, due or payable, whether before or after the filing of a bankruptcy, insolvency or similar proceeding under applicable federal, state, foreign or other law and whether or not an allowed claim in any such proceeding.

2. Guaranty of Payment

(a) Each Guarantor, jointly and severally, hereby unconditionally and irrevocably guarantees the full and prompt payment and performance to Purchasers and Agent, on behalf of itself and in its capacity as agent for the benefit of Purchasers, when due, upon demand, at maturity or by reason of acceleration or otherwise and at all times thereafter, of any and all of the Obligations.

(b) Each Guarantor acknowledges that valuable consideration supports this Guaranty, including, without limitation, the consideration set forth in the recitals above, as well as any commitment to lend, extension of credit or other financial accommodation, whether heretofore or hereafter made by Purchasers to any Company; any extension, renewal or replacement of any of the Obligations; any forbearance with respect to any of the Obligations or otherwise; any cancellation of an existing guaranty; any purchase of any Company’s assets by any Purchaser or Agent; or any other valuable consideration.

(c) Each Guarantor agrees that all payments under this Guaranty shall be made in United States currency and in the same manner as provided for the Obligations.

(d) Notwithstanding any provision of this Guaranty to the contrary, it is intended that this Guaranty, and any interests, liens and security interests granted by Guarantors as security for this Guaranty, not constitute a “Fraudulent Conveyance” (as defined below) in the event that this Guaranty or such interest is subject to the Bankruptcy Code or any applicable fraudulent conveyance or fraudulent transfer law or similar law of any state. Consequently, Guarantors, Agent and Purchasers agree that if this Guaranty, or any such interests, liens or security interests securing this Guaranty, would, but for the application of this sentence, constitute a Fraudulent Conveyance, this Guaranty and each such lien and security interest shall be valid and enforceable only to the maximum extent that would not cause this Guaranty or such interest, lien or security interest to constitute a Fraudulent Conveyance, and this Guaranty shall automatically be deemed to have been amended accordingly at all relevant times. For purposes hereof, “Fraudulent Conveyance” means a fraudulent conveyance under Section 548 of the Bankruptcy Code or a fraudulent conveyance or fraudulent transfer under the provisions of any applicable fraudulent conveyance or fraudulent transfer law or similar law of any state, as in effect from time to time.

(e) Each provision of this Guaranty and the obligations of each party hereto shall be subject to, and modified as necessary by, the rights and obligations of the parties pursuant to the Prior Security Agreement and the Senior Security Interest. The first priority of the Senior Security Interest is hereby acknowledged and affirmed, and in the event of an apparent conflict between the terms of this Guaranty and the terms of the Prior Security Agreement, the Prior Security Agreement shall prevail and the terms of this Guaranty shall be deemed amended as necessary to give effect to the priority of the Senior Security Interest. Upon payment of the Senior Notes, the Notes shall have a first priority security interest without the necessity for any additional documentation and be deemed to have a senior security interest in the Collateral.

3. Costs and Expenses. Each Guarantor, jointly and severally, agrees to pay on demand, all reasonable costs and expenses of every kind incurred by any Purchaser or Agent: (a) in enforcing this Guaranty, (b) in collecting any of the Obligations from any Company or any Guarantor, (c) in realizing upon or protecting or preserving any collateral for this Guaranty or for payment of any of the Obligations, and (d) in connection with any amendment of, modification to, waiver or forbearance granted under, or enforcement or administration of any Transaction Document or for any other purpose in connection with any Transaction Document, in each case, to the extent Purchaser or Agent may take such action pursuant to the terms and conditions of this Agreement. “Costs and expenses” as used in the preceding sentence shall include, without limitation, reasonable attorneys’ fees incurred by any Purchaser or Agent in retaining legal counsel for advice, suit, appeal, any insolvency or other proceedings under the Bankruptcy Code or otherwise, or for any purpose specified in the preceding.

4. Nature of Guaranty: Continuing, Absolute and Unconditional.

(a) This Guaranty is and is intended to be a continuing guaranty of payment of the Obligations, and not of collectability, and is intended to be independent of and in addition to any other guaranty, endorsement, collateral or other agreement held by Purchasers or Agent therefor or with respect thereto, whether or not furnished by a Guarantor. None of Purchasers and Agent shall be required to prosecute collection, enforcement or other remedies against any Company, any other Guarantor or guarantor of the Obligations or any other person or entity, or to enforce or resort to any of the Collateral or other rights or remedies pertaining thereto, before calling on a Guarantor for payment. The obligations of each Guarantor to repay the Obligations hereunder shall be unconditional. Guarantor shall have no right to exercise any right of subrogation, reimbursement, indemnity, exoneration, contribution or any other claim which it may now or hereafter have against any Company in connection with this Guaranty until the termination of this Guaranty in accordance with Section 8 below, and hereby waives any benefit of, and any right to participate in, any security or collateral given to Purchasers to secure payment of the Obligations, and each Guarantor agrees that it will not take any action to enforce any obligations of any Company to such Guarantor prior to the Obligations being finally and irrevocably paid in full in cash, provided that, in the event of the bankruptcy or insolvency of any Company, to the extent the Obligations have not been finally and irrevocably paid in full in cash, Agent, for the benefit of itself and Purchasers, and Purchasers shall be entitled notwithstanding the foregoing, to file in the name of any Guarantor or in its own name a claim for any and all indebtedness owing to a Guarantor by such Company (exclusive of this Guaranty), vote such claim and to apply the proceeds of any such claim to the Obligations.

(b) For the further security of Purchasers and without in any way diminishing the liability of the Guarantors, following the occurrence and during the continuance of an Event of Default, all debts and liabilities, present or future, of the Companies to the Guarantors, and all monies received from any Company or for its account by the Guarantors in respect thereof shall be received in trust for Purchasers and Agent and promptly following receipt shall be paid over to Agent, for its benefit and in its capacity as Agent for the benefit of Purchasers, until all of the Obligations have been paid in full in cash. This assignment and postponement is independent of and severable from this Guaranty and shall remain in full effect whether or not any Guarantor is liable for any amount under this Guaranty.

(c) This Guaranty is absolute and unconditional and shall not be changed or affected by any representation, oral agreement, act or thing whatsoever, except as herein provided. This Guaranty is intended by the Guarantors to be the final, complete and exclusive expression of the guaranty agreement among the Companies (as limited by the express terms of this Guaranty), the Guarantors, the Agent and Purchasers. No modification or amendment of any provision of this Guaranty shall be effective against any party hereto unless in writing and signed by a duly authorized officer of such party. This Guaranty, together with the other Transaction Documents, supersedes all other prior oral or written agreements between each Purchaser, the Guarantors, the Agent, their Affiliates and Persons acting on their behalf with respect to the matters discussed herein, and this Guaranty, together with the other Transaction Documents and the other instruments referenced herein and therein, contain the entire understanding of the parties with respect to the matters covered herein and therein and, except as specifically set forth herein or therein, neither any Guarantor, the Agent nor any Purchaser makes any representation, warranty, covenant or undertaking with respect to such matters. As of the date of this Guaranty, there are no unwritten agreement between the parties with respect to the matters discussed herein. No provision of this Guaranty may be amended, modified or supplemented other than by an instrument in writing signed by the parties hereto.

(d) Each Guarantor hereby releases each Company from all, and agrees not to assert or enforce (whether by or in a legal or equitable proceeding or otherwise) any, “claims” (as defined in Section 101(5) of the Bankruptcy Code), whether arising under any law, ordinance, rule, regulation, order, policy or other requirement of any domestic or foreign Governmental Authority or any instrumentality or agency thereof, having jurisdiction over the conduct of its business or assets or otherwise, to which the Guarantors are or would at any time be entitled by virtue of its obligations hereunder, any payment made pursuant hereto or the exercise by any Purchaser or Agent of its rights with respect to the Collateral, including any such claims to which such Guarantors may be entitled as a result of any right of subrogation, exoneration or reimbursement.

5. Certain Rights and Obligations.

(vi) take advantage or refrain from taking advantage of any security or accept or make or refrain from accepting or making any compositions or arrangements when and in such manner as Agent, in its sole discretion, may deem appropriate; and generally do or refrain from doing any act or thing which might otherwise, at law or in equity, release the liability of such Guarantor as a guarantor or surety in whole or in part, and in no case shall Purchasers or Agent be responsible or shall any Guarantor be released either in whole or in part for any act or omission in connection with Purchasers or Agent having sold any security at less than its value.

Each Guarantor further agrees that, to the extent that any Company makes a payment or payments to Purchasers or Agent on the Obligations, or Purchasers or Agent receive any proceeds of collateral securing the Obligations or any other payments with respect to the Obligations, which payment or receipt of proceeds or any part thereof is subsequently invalidated, declared to be fraudulent or preferential, set aside or required to be returned or repaid to any Company, its estate, trustee, receiver, debtor in possession or any other person or entity, including, without limitation, the Guarantors, under any insolvency or bankruptcy law, state or federal law, common law or equitable cause, then to the extent of such payment, return or repayment, the obligation or part thereof which has been paid, reduced or satisfied by such amount shall be reinstated and continued in full force and effect as of the date when such initial payment, reduction or satisfaction occurred, and this Guaranty shall continue in full force notwithstanding any contrary action which may have been taken by any Purchaser or Agent in reliance upon such payment, and any such contrary action so taken shall be without prejudice to any Purchaser’s or Agent’s rights under this Guaranty and shall be deemed to have been conditioned upon such payment having become final and irrevocable.

(i) any and all indebtedness or other moneys due or to become due to any Guarantor by any Purchaser or Agent in any capacity; and

(ii) any credits or other property belonging to any Guarantor (including all account balances, whether provisional or final and whether or not collected or available) at any time held by or coming into the possession of any Purchaser or Agent, or any affiliate of any Purchaser or Agent, whether for deposit or otherwise; whether or not the Obligations or the obligation to pay such moneys owed by any Purchaser or Agent is then due, and the applicable Purchaser or Agent shall be deemed to have exercised such right of set off immediately at the time of such election even though any charge therefor is made or entered on such Purchaser’s or Agent’s records subsequent thereto. Agent agrees to notify such Guarantor in a reasonably practicable time of any such set-off; however, failure to so notify such Guarantor shall not affect the validity of any set-off.

(d) No course of dealing between any Company or any Guarantor and Purchasers or Agent and no act, delay or omission by Purchasers or Agent in exercising any right or remedy hereunder or with respect to any of the Obligations shall operate as a waiver thereof or of any other right or remedy, and no single or partial exercise thereof shall preclude any other or further exercise thereof or the exercise of any other right or remedy. Any Purchaser or Agent may remedy any default by any Company under any agreement with any Company or with respect to any of the Obligations in any reasonable manner without waiving the default remedied and without waiving any other prior or subsequent default by any Company.

Each Guarantor hereby irrevocably submits to the exclusive jurisdiction of the state and federal courts sitting in the City of New York, borough of Manhattan, for the adjudication of any dispute hereunder or in connection herewith or with any transaction contemplated hereby or discussed herein, and hereby irrevocably waives, and agrees not to assert in any suit, action or proceeding, any claim that it is not personally subject to the jurisdiction of any such court, that such suit, action or proceeding is brought in an inconvenient forum or that the venue of such suit, action or proceeding is improper. Each Guarantor hereby irrevocably waives personal service of process and consents to process being served in any such suit, action or proceeding by mailing by registered or certified mail a copy thereof to such party at the address for such notices to it under this Guaranty and agrees that such service shall constitute good and sufficient service of process and notice thereof as of the date that is five (5) business days after the mailing thereof. Nothing contained herein shall be deemed to limit in any way any right to serve process in any manner permitted by law.

12. Notices. All notices, approvals, requests, demands and other communications hereunder shall be delivered or made in the manner set forth in, and shall be effective in accordance with the terms of, the Purchase Agreement or, in the case of communications to the Agent, directed to the notice address set forth in the Security Agreement; provided, that any communication shall be effective as to any Guarantor if made or sent to BTCS in accordance with the foregoing.

Each Guarantor shall indemnify the Agent and the Purchasers, within ten (10) days after written demand therefor, for the full amount of any Indemnified Taxes paid by the Agent or Purchasers, as applicable, on or with respect to any payment by or on account of any obligation of such Guarantor under this Guaranty and the other Transaction Documents (including Indemnified Taxes or imposed or asserted on or attributable to amounts payable under this Section 14) and any penalties, interest and reasonable expenses arising therefrom or with respect thereto, whether or not such Indemnified Taxes were correctly or legally imposed or asserted by the relevant Governmental Authority. A certificate of the Agent or any Purchaser as to the amount of such payment or liability under this Section 14 shall be delivered to such Guarantor and shall be conclusive absent manifest error.

17. Counterparts; Headings. This Guaranty may be executed in two or more identical counterparts, all of which together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to each other party; provided that a facsimile, .pdf or similar electronically transmitted signature shall be considered due execution and shall be binding upon the signatory thereto with the same force and effect as if the signature were an original signature. The headings in this Guaranty are for convenience of reference only and shall not alter or otherwise affect the meaning hereof.

18. Rights of Contribution. The Guarantors hereby agree as among themselves that, if any Guarantor shall make an Excess Payment (as defined below), such Guarantor shall have a right of contribution from each other Guarantor in an amount equal to such other Guarantor’s Contribution Share (as defined below) of such Excess Payment. The payment obligations of any Guarantor under this Section 16 shall be subordinate and subject in right of payment to the Obligations until such time as the Obligations have been paid in full in cash and all commitments to lend under the Purchase Agreement have expired or terminated, and none of the Guarantors shall exercise any right or remedy under this Section 16 against any other Guarantor until such Obligations have been paid in full in cash and all commitments to lend under the Purchase Agreement have expired or terminated. For purposes of this Section 16, (a) “Excess Payment” shall mean the amount paid by any Guarantor in excess of its Ratable Share of any Obligations; (b) “Ratable Share” shall mean, for any Guarantor in respect of any payment of Obligations, the ratio (expressed as a percentage) as of the date of such payment of Obligations of (i) the amount by which the aggregate present fair salable value of all of its assets and properties exceeds the amount of all debts and liabilities of such Guarantor (including contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the obligations of such Guarantor hereunder) to (ii) the amount by which the aggregate present fair salable value of all assets and other properties of the Companies and the Guarantors exceeds the amount of all of the debts and liabilities (including contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the obligations of the Guarantors hereunder) of the Companies and the Guarantors, provided, however, that, for purposes of calculating the Ratable Shares of the Guarantors in respect of any payment of Obligations, any Guarantor that became a Guarantor subsequent to the date of any such payment shall be deemed to have been a Guarantor on the date of such payment and the financial information for such Guarantor as of the date such Guarantor became a Guarantor shall be utilized for such Guarantor in connection with such payment; and (c) “Contribution Share” shall mean, for any Guarantor in respect of any Excess Payment made by any other Guarantor, the ratio (expressed as a percentage) as of the date of such Excess Payment of (i) the amount by which the aggregate present fair salable value of all of its assets and properties exceeds the amount of all debts and liabilities of such Guarantor (including contingent, subordinated, unmatured, and unliquidated liabilities, but excluding the Obligations) of the Companies and the Guarantors other than the maker of such Excess Payment; provided, however, that, for purposes of calculating the Contribution Shares of the Guarantors in respect of any Excess Payment, any Guarantor that became a Guarantor subsequent to the date of any such Excess Payment shall be deemed to have been a Guarantor on the date of such Excess Payment and the financial information for such Guarantor as of the date such Guarantor became a Guarantor shall be utilized for such Guarantor in connection with such Excess Payment. This Section 16 shall not be deemed to affect any right of subrogation, indemnity, reimbursement or contribution that any Guarantor may have under law against any Company in respect of any payment of Obligations.
